To all whom it 'may concern:

Beit known .that I, ARTHUR B. CLARK, a citizen of the United States,residing at Dyerville, in the `county of Humboldt and State ofCalifornia, have invented lnew and useful Improvements in Stoves, `ofwhich the following is a specification.

This invention'relates Vto improvements in stoves and has for an yobyectthe provision of a stove of novel construction, which may be quicklyassembled, due -to the intertting of the various parts, theintermediateparts beingheld in position by the outer parts, so that amimimum amount of labor is required in its manufacture and cost ofproduction thus materially reduced.

Another object of the-invention is the provision of a stove whiohmay beusedeither for cooking food in the usual manner or lin which the foodmay be partially cooked and the source of heat-cut oil vand the retainedheat utilized to finish the cooking after the manner'of a Ltirelesscooker. l

Another object is the provision of a stove which maybe used .either forcooking or heatingpurposes .and Vwhen used for the former, heat will beretained .in the stove and overheating of the room prevented, while theheat thus .conserved will materially reduce the costof operating thestove.

With the above and other objects vin view,

the invention further includes the following novel features and detailsofconstruction, to be hereinafter more fully described, illustrated inthe accompanying drawings and pointed .out in the appended claims.

In the drawings:

Figure 1 is a perspective view of a. stove embodying the `presentinvention. Y

Figure 2 is a vertical sectional view on the line 2-2 of Figure 1.

Figure 3 is a horizontal section on the line 3 3 of Figure 1.

Figure 4 is an enlarged fragmentary sectional view on the line 4-4 ofFigure 6.

Figure 5 is a detail perspective view of one of the flue closures.

Figure 6 is a top plan view of the stove.

Referring to the drawings in detail, wherein like characters ofreference denote corresponding parts, the reference character 10indicates an outer casing which is preferably of cylindrical form. Thiscasing is divided by partitions 11 and 12 into a lower fire or burnery,chamber 13, an upper heat chamber 14 and an intermediate chamber, thelatter providingan oven 15.

The fire -or burner chamber 13 has the lower `.edge of its side wallsbent outwardly :to provide abase flange 16 and-is provided withanopening 17 ,by ymeans of which access 4may behad to the interior forthe purpose 4ot controlling a burner 118, .whichfmay be of the usual orany preferred construction.

The walls of the heat chamber 14 andthe 'oven-15 Iare insulatedxfor thepurpose of retaining the heat of the burner 18 and for this purpose Vthelowerfpartition 11 is formed of a lower plate 19 whichis provided with-aperipherial fiange 20, the said flange being riveted vor otherwisesecured to :the outer casing 10 as indicated at 21. The Aplate 19 thusforms ,thetop wall of the burner ychamber13. Supported upon-the top oftheplate 19 is a layer-of insulating material 22, which is preferablyformed of 85% lmagnesiav and overlying this insulating `material 122 is'a plate 23, the plates 19,"231and the insulating material 22thuslforming `the Vpartition .111. The partition 11 iis yprovided withvan opening 24 which forms a passage forthev heat from the burner 18"into the `oven 15, fthe walls of this opening being formed byv bendingupwardly a flange from-the `pla'lte 19 and downwardly a vflange from'theplate T23 and thus protecting l'the lining :22.

Mounted iupon the upper surface of "the partition 11 within the oven 15is an inner casing '-25 which is spaced from the outer casing and thespacezthus provided is :filled with van insulating lining 126 which is`preferably of/the same .character las 'the lining 22, the said lining26also -restingupon `the upper `surface of the partition 11.

The .lining y2.6 and the inner casing Y25 terminate short of the top ofthe outer casing 10 and provide a shoulder for the partition 12. Thislast named partition is rformed with a lower plate 27 which forms wisesecured tothe flange 36 which extends manner of the usual stove holesand plates.`

from the outer casing 10. The cover 34 is provided with an insulatinglining 37 which is held in position between the said cover and the plate35, the latter being suitably secured to the plate 34 and resting uponthe upper edges of the lining 31and inner cas ing 32. Thus, the stovemay be readily assembled by riveting the lower plate 19 of the lowerpartition 11 and the casing 10 and inserting the interior parts of thestove, so that after the top-34 is riveted in position the said interiorparts will be held against movement without auxiliary' fasteningdevices. Y

The topV of the stove is provided with openings 38 which are preferablyformed similarly to the openings 24 and 30 and are adapted vto be closedby plates 39 after the The oven 15 is provided with an opening 40V whichmay be'closed by a hinge-d door 41. This door is formed of an outerplate 42 which is of larger area than the opening 40 and carries aninsulating lining 43 which is secured by means of a anged container 44.An asbestos packing 45 is preferably secured around the flange providedby the overlapping part o-f the plate 42 so that when the door is closedescape of the heat from the oven is prevented.

v The oven 15 preferably contains a 46 which may be positioned uponsupportsf47 Vand 48.

It will be apparent that the st ove may be used for cooking in the usualmanner and when so used7 overheating of the room will be prevented dueto the insulated walls of the heat chamber and the oven and thus aminimum amount Vof heat will be required for cooking If desired, thefood may be partially cooked. and the source of heat cut off, whereupon,the passages 24 and 30 may be covered by a closure 49 and the operationgrate vof cooking continued after the manner of grate I the ordinarytireless cooker. `When it is desired to use the stove as a heater, theoven door may be opened and the heat thus permitted to escape from theside of the stove.

The invention is susceptible of various changes in its forni,proportions and minor details of construction and the right is herefdescribed the invention what is sulating lining between the inner and'outerl casings, said lining and casing terminating short. of the topofthe outer casing and` forming a shoulder for supporting the top of theoven, an insulating lining for the ovenrtop, and insulated walls forrthe top andY sides of the heat chamber.

2. A stove comprising an outer casing divided horizontally by spacedinsulated i partitions to form a lower chamber adapted.

to contain a sour-ce of heat, a top heat chamber and an intermediatechamber defining an oven, an inner casing located within the oven andspaced from the outer casing, an insu-1V lated lining between the innerand outer casings7 said inner casing and limng having their lower endsresting upon the lowermost` partition and providing a, shoulder at theirinner casing located'` within the heat; cham# ber an-d spaced from theouter casing, an insulating lining therefor, said inner casing andlining having one end abutting'tlie cover and the opposite end abuttingthe upper partition and heat passages 'in said partition.

`upper ends for the upper partition. an nsulating cover having openingstherein and secured to the top of the outer casing, an

Tn testimony whereof I afiix my signature.
